What is Germination
As the mother gives birth to a child, the seed gives rise to a new plant. The process in which a plant takes birth or comes out of a seed is called as germination. There is no alternate process of germination. This process is mandatory for the production of a new plant. This law is applicable to each and every kind of living organism other than the animals.
What Affects the Process of Germination
Several things other than the seed required for successful germination. Any of those missed may lead to unsuccessful germination or partial germination. Let us discuss about those factors.
Water – Water is a must for the germination. Germination can’t be thought of without water. First of all, a seed need to be soaked in water for the germination. A seed become soft, when soaked in water. The outer crusts of the seeds are generally rigid and those becomes soft, when comes in contact with the water. The embryo of a new plant comes into life inside the seed before the germination. The embryo of the plant requires water to live and germinate. After the germination, the plant tiny plant also requires water. A plat only becomes able to prepare its food, when it gets water; so water is the most important thing required for the process of absorption.
Oxygen – Oxygen is the second most important thing required for the germination. Embryo of a seed requires oxygen for aerobic respiration. In fact, oxygen hided in the soil pores supplies the required energy to the plant embryo, till it gets leaves. This is why, for the germination the seeds should be placed in abundance of oxygen. If anyone is putting the seeds into soil for the germination, then he or she should make the soil porous first so that air could get into the soil.
Sunlight – Sunlight is also required for the process of germination. In fact, sunlight is not really necessary for the process of germination but after the germination, the small plant requires sunlight to prepare its food; so that it could grow. There are some seeds, which germinates only after getting exposed to sufficient sunlight.
Temperature – Though, there is very slight effect of outside temperature on the process of germination, but there is a temperature range for each and every seed within which a seed can germinate. Above a certain temperature a seed can’t germinate. At the same time, below a certain temperature, the seeds also can’t germinate. These threshold temperatures vary for different kinds of seeds.
Conclusion – From the above discussion, it becomes clear that germination is a very sensitive process and it requires very close attention. If a person wants seeds to be germinated, then he or she should take proper care of the seeds by keeping the above mentioned points in mind.
